To @ZZ whom, t may concern: f

Be it known that I, ADOLPHUS RIGGS, a citizen of the United States,'residing at Kennett, in the county of Dunklin and AState of Missouri, have invented certain new and useful Improvements in Saw-Gummin g Machines, of which the following is a specification.

My present invention relates to saw-gumming machines, the advantages and construction of which will be hereinafter set forth, reference being had to the annexeddrawings, wherein Figure 1 is a perspective view of the `machine, and Figs. 2 and 3 vertical sectional views.

. The object of my invention is to provide a simple and at the same time highly-efficient machine and one which will accurately gage its work.

The body proper of the machine consists of two sections A A, each section being formed with a downwardly-projecting leg B, having an elongated slot C therein.

From the outer corners of each of the sections A there extend upright arms D, the arms being of equal height andconnected to each other by a plate E. This plate is of such dimensions that when the parts are assembled thereis left a space'between the inner faces of sections A and the legs B of such width as to accommodate a saw-blade.

Each of the sections A has a web F formed integral therewith contiguous to one of the uprights D, and secured to the webs at their proximate edges are arms G. These arms G extend out from the machine at right angles thereto and are provided with elongated slots or openings H, through which extends a bolt I, provided with a thumb-nut J. A similar bolt K, having thuinbfnut L,' is provided for the slot C.

Mounted between each pair of uprights D is a sliding block M, the blocks being directly connected by a cross bar or head N. A threaded spindle O, working inthe plate E, has its lower end swiveled in the cross-bar N, and when turned serves to raise or lower said cross-bar and the sliding block M.

Journaled in the blocks M- is a shaft P, carrying a cutter or mi1ling-tool Q, held in place by a washer R and nut S, the'cutter being in alinement with the slot or opening between the sections A. The shaft is provided with a suitable crank T for imparting motion thereto. j l

In use the saw-blade (shown in dotted lines, Fig. 2, and full lines, Figi 3) is placed orpassed in between the sections A and the depending legs B thereof, theboglt K being so regulated as to form a supportfor the lower edge thereof and to clamp the blade between the legs or arms. Bolt I is then adjusted so as to form a gage or stoprby engaging with the forward teeth and bringing the tooth which is to be operated upon to a proper position beneath the cutter. The cutter is then lowered and rotary motion imparted thereto, the cutter being fed down to the required or desired depth as the cutting progresses. When a tooth has been properly dressed, the blade is drawn back slightly and the` cutter elevated, when by tipping the machine relatively to the blade, or vice versa, the forward tooth will become disengaged with bolt I and the blade may again be fed forward, bringing a new tooth to place beneath the cutter.

By adjusting the bolt I toward or from the cutter it will be seen that teeth of `different I size may be gaged and out out, as desired. So too by elevating or lowering bolt K in the slot C varying widths of saws may be held in their proper position relative to the cutter.

I-Iaving thus described my invention,what I claim isl. In a saw-gumming machine, the combination of a frame comprising two main sections provided with depending legs having elongated slots formed therein; a bolt adjustably mounted in said slots; a cutter mounted in the upper portion'of the frame; means for raising and lowering the cutter; means for imparting motion thereto; and a gage located to one side of rthe cutter designed to engage thehteeth of the saw-blade.

2. In a saw-gumming machine, the combination of a frame comprising two main sections provided with depending legsjhaving elongated slots formed therein; a bolt adjustably mounted in said slots; a cutter mounted in the upper portion of theframe; meansfor raising and lowering the cutter; means for` imparting motion thereto; slotted arms eX- IOO tending out from the frame at approximately right angles thereto; and an adjustable bolt mounted in said arms.

3. In a saw-gumming machine, the combination of a frame comprising two main seotions A provided with depending legs B having elongated slots formed therein; a 'loolt mounted in said slots; slotted arms H extending ont from the frame; a bolt mounted in said arms; a cutter; and means for raising and lowering the cutter, substantially as described.

4. In a saw-gumming machine, the combination of a frame comprising two main seo-` tions A provided with depending legs B having elongated slots formed therein a bolt vmounted in said slots; uprights D extending up from sections A; a plate E oonneotin g said sections; .sliding blocks M mounted between said uprights and connected by a cross-bar N; a threaded spindle working in said plate E and swiveled in the cross-bar a shaft journaled in the blocks M; a out-ter carried by said shaft slotted arms H extending out from the frame at right angles thereto; and a bolt mounted in said arms.

In witness whereof I hereunto set my hand in the presence of two witnesses.
